Family Travel Visa Checklist: Passports, Consent Letters & More

2026-07-17

Traveling internationally as a family adds documentation layers that solo travelers never face. Missing a single child-consent letter or an expired minor passport can end a trip at the gate. This checklist keeps your family's paperwork airtight.

Every family member needs their own passport

Children — including newborns — require their own passport for international travel. Minor passports are typically valid for fewer years than adult ones, so check expiry dates early and remember the six-month validity rule applies to children too.

When consent letters are required

Many countries require a notarized consent letter when a child travels with one parent or with someone other than a parent, to combat child trafficking. Even where not strictly mandatory, carrying one prevents lengthy questioning at the border.

• Full names and passport details of the child and accompanying adult.
• Contact details and signature of the non-traveling parent(s).
• Travel dates and destinations.

The family pre-departure checklist

Confirm every passport is valid for six months beyond your return, check visa requirements for each nationality in the family, prepare consent letters where needed, and carry copies of birth certificates linking children to parents.

Frequently asked questions

Do babies need a passport to travel internationally?

Yes — every child, including infants, needs their own valid passport for international air travel.

Is a child consent letter always required?

Not everywhere, but many countries require or strongly recommend one when a child travels with only one parent or a non-parent. Carrying one avoids problems.
